How to write code for DFT in Matlab?

Compute the DFT of the signal and the magnitude and phase of the transformed sequence.
Decrease round-off error when computing the phase by setting small-magnitude transform values to zero. f = (0:length(y)-1)*100/length(y); % Frequency vector subplot(2,1,1) plot(f,m) title('Magnitude') ax = gca; ax.

How to write FFT code in Matlab?

Fs = 44100; % Sampling frequency T = 1/Fs; % Sampling period t = -0.5:T:0.5; % Time vector L = length(t); % Signal length X = 1/(0.4*sqrt(2*pi))*(exp(-t. ^2/(2*(0.1*1e-3)^2))); Plot the pulse in the time domain.
The execution time of fft depends on the length of the transform.

How to write FFT code in Matlab?

Fractional Fourier transforms transform a signal (either in the time domain or frequency domain) into the domain between time and frequency: it is a rotation in the time–frequency domain.
I'm using the fractional Fourier transform implementation called frft2. m found here.
